Subscription updates in multiple device language models

ABSTRACT

Systems and methods for intelligent language models that can be used across multiple devices are provided. Some embodiments provide for a client-server system for integrating change events from each device running a local language processing system into a master language model. The change events can be integrated, not only into the master model, but also into each of the other local language models. As a result, some embodiments enable restoration to new devices as well as synchronization of usage across multiple devices. In addition, real-time messaging can be used on selected messages to ensure that high priority change events are updated quickly across all active devices. Using a subscription model driven by a server infrastructure, utilization logic on the client side can also drive selective language model updates.

BACKGROUND

There are a wide variety of language recognition systems that are designed to use one or more input modes. Typically, these input modes include a text input mode, speech input mode, and/or handwriting input mode. One of the fundamental objectives underlying these language recognition systems is to enable users to create text using one or more input modes with increased reliability at increased rates. The text input mode, for example, often allows increased input rates by enabling the user to perform actions with less precision than is required by comparable systems. In addition, this mode often provides a predicative completion feature that suggests word completion. The voice and handwriting input modes utilize a different set of input actions that some users may find easier and faster than typing. These inputs are then translated to text.

In general, language recognition systems rely upon local language models with a lexicon of textual objects that can be generated by the system based on the input actions performed by the user. However, since each user is different, these language models dynamically evolve in different ways based on each user's interactions. Moreover, the users of the language recognition systems often have multiple devices on which to use the language recognition systems. This results in the users having to independently train a language model for each device. As such, techniques are needed that provide language models that can be used across multiple devices.

DETAILED DESCRIPTION

Various embodiments of the disclosed language processing system and methods generally relate to user entry of information into a system with an input device. In particular, some embodiments provide for intelligent language models that can be used across multiple devices. Traditional language recognition systems rely upon local language models with a lexicon of textual objects that can be generated by the system. In some cases, the devices running the language recognition system uses the language models to map input actions performed by the user to one or more of these textual objects in the lexicon. These models are often dynamic and grow and learn as they are used, allowing a user to improve the baseline prediction with usage and teaching.

With the proliferation of computing devices, it is not uncommon for users to have multiple devices and, as a result, have multiple local language models. With traditional language recognition systems, each device would need to individually learn or develop a customized local language model based on user inputs with each device. Moreover, a number of variables affect the accuracy with which these language recognition systems recognize and map the inputs to the textual objects. Prominent among these factors is whether the textual object resides within the lexicon and the frequency of use of the textual object. For example, if a word is not frequently used, a text input system might misrecognize the word, favoring one that is statistically more likely to be utilized. Among the words that are commonly misrecognized are proper names, such as those for people, streets, restaurants, and other words that have a special relevance in personal messages like voicemails. As a result, the language model in any one device may have a less than desirable response because the language model has not been trained with all of the user's inputs.

In contrast, the language processing systems and methods disclosed herein create a master language model, synchronize changes from an individual device's model with the master language model, and synchronize the change from the master language model to the other devices associated with the user. The master language model may be stored “in the cloud,” such as in a remote server or other device. Maintaining a master language model allows a user to create a custom language model that moves with the user between devices, as well as keeps multiple devices synchronized. In addition, the use of a master language model enables new devices to adopt the most current language model. In some embodiments, a server-based subscription model for language updates can be utilized by a client running on a user's device, which determines the most optimal update scheduling for language models maintained in each local device.

Under some situations (e.g., due to connection type or heavy usage), it may be impractical to consistently synchronize events on a local device with the master language model. Various embodiments provide the ability to selectively deliver some events to the master language model in real-time (or near real-time) in order to improve immediate prediction on the other secondary devices. In at least one embodiment, a messaging system can be used to prioritize when to distribute events to local devices. For example, the messaging system can determined which events are of high importance and immediately enter that event into the language model. The messaging system can utilize a real-time (or near real-time) message bus between multiple clients and a server, or set of servers, enabling the ability to synchronize language model change events to enhance the input experience for a user across multiple devices.

In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of embodiments of the present invention. It will be apparent, however, to one skilled in the art that embodiments of the present invention may be practiced without some of these specific details. While, for convenience, embodiments of the present invention are described with reference to cloud-based master language models, embodiments of the present invention are equally applicable to various other networking paradigms where a master language model may reside.

The techniques introduced here can be embodied as special-purpose hardware (e.g., circuitry), as programmable circuitry appropriately programmed with software and/or firmware, or as a combination of special-purpose and programmable circuitry. Hence, embodiments may include a machine-readable medium having stored thereon instructions which may be used to program a computer (or other electronic devices) to perform a process. The machine-readable medium may include, but is not limited to, floppy diskettes, optical disks, compact disc read-only memories (CD-ROMs), magneto-optical disks, ROMs, random access memories (RAMs), erasable programmable read-only memories (EPROMs), electrically erasable programmable read-only memories (EEPROMs), magnetic or optical cards, flash memory, or other type of media/machine-readable medium suitable for storing electronic instructions.

The phrases “in some embodiments,” “according to some embodiments,” “in the embodiments shown,” “in other embodiments,” and the like generally mean the particular feature, structure, or characteristic following the phrase is included in at least one implementation of the present invention, and may be included in more than one implementation. In addition, such phrases do not necessarily refer to the same embodiments or different embodiments.

FIG. 1 illustrates an example of a computing environment 100 in which embodiments of the present invention may be utilized. As illustrated in FIG. 1, a language recognition system may be operating on one or more mobile devices 110 a-n (such as a mobile phone, tablet computer, mobile media device, mobile gaming device, vehicle-based computer, etc.), one or more computing devices (such as computer 120), and other devices capable of receiving user inputs (e.g., such as navigation system 130). Each of these devices can include various input mechanisms (e.g., microphones, keypads, and/or touch screens) to receive user interactions (e.g., voice, text, and/or handwriting inputs). Each language recognition system on these devices can be running a local language model.

As illustrated in FIG. 1, these devices can communicate with master language processing system 140 through one or more wired or wireless, public or private, networks 150. In accordance with various embodiments of the present invention, master language processing system 140 builds a master language model by applying the changes received from multiple language models that are running locally on the mobile devices. As a result, the master language model is a model (i.e., a single model or a combination of multiple models) generated specifically for the end user from the interactions the end user has with each of the devices associated with the end user.

In accordance with various embodiments, the master language model may include multiple models such as static language model 160 and dynamic language model 170. Static language model 160 is a word list generated for a language based on general language use. In some embodiments, infrequently used words (e.g., dinosaur names or street names) can be added permanently or temporarily as a new partition or language model based on location or other triggering event. In contrast, dynamic language model 170 receives change events (e.g., add a word, delete a word, word corrections, n-grams, and word count) from each device associated with the end user. Change events are typically processed in the order that they occurred in order to update the dynamic language model (e.g., in real-time or near real-time). However, in some embodiments, change events can be processed out of order to update the dynamic language model. For example, more important change events may be prioritized for processing before less important change events.

FIG. 2 illustrates a set of components for a local language processing system 200. According to the embodiments shown in FIG. 2, local language processing system 200 can include memory 205, one or more processors 210, power supply 215, input devices 220, event detection module 225, event aggregation module 230, local language models 235, prioritization module 240, synchronization module 245, communications module 250, queuing module 255, and graphical user interface (GUI) generation module 260. Other embodiments of the system may include some, all, or none of these modules and components along with other modules, applications, and/or components. Still yet, some embodiments may incorporate two or more of these modules and components into a single module and/or associate a portion of the functionality of one or more of these modules with a different module. For example, in one embodiment, prioritization module 240 and queuing module 255 can be combined into a single module for prioritizing event data transfers.

Memory 205 can be any device, mechanism, or populated data structure used for storing information. In accordance with some embodiments of the present system, memory 205 can encompass any type of, but is not limited to, volatile memory, nonvolatile memory, and dynamic memory. For example, memory 205 can be random access memory, memory storage devices, optical memory devices, media magnetic media, floppy disks, magnetic tapes, hard drives, SDRAM, RDRAM, DDR RAM, erasable programmable read-only memories (EPROMs), electrically erasable programmable read-only memories (EEPROMs), compact disks, DVDs, and/or the like. In accordance with some embodiments, memory 205 may include one or more disk drives, flash drives, one or more databases, one or more tables, one or more files, local cache memories, processor cache memories, relational databases, flat databases, and/or the like. In addition, those of ordinary skill in the art will appreciate many additional devices and techniques for storing information which can be used as memory 205

Memory 205 may be used to store instructions for running one or more applications or modules on processors 210. For example, memory 205 could be used in one or more embodiments to house all or some of the instructions needed to execute the functionality of event detection module 225, event aggregation module 230, local language models 235, prioritization module 240, synchronization module 245, communications module 250, queuing module 255, and/or GUI generation module 260. Memory 205, processors 210, and other components (e.g., input devices 220) may be powered by power supply 215 (e.g., a battery or other power source).

Event detection module 225 can use one or more input devices 220 (e.g., keyboard, touchscreen, or microphone) to detect one or more change events associated with local language models running on each computing device 110-130. Change events arise as a result of a user's interaction with a language processing system on a local device. A change event can be used to modify the local language model. Some change events may have a large impact on the local language model (e.g., when adding a word), while other change events may have little to no effect (e.g., using a word which already has a high frequency count). Change events can include data points which can be used by the system to process changes which modify the language model. Examples of events that can be detected include new word events, delete word events, mark use events, mark nonuse events, adjust quality events, delete language events, new word pair events, new n-gram events, location events, and many other events that can be used for developing a dynamic language model. In some embodiments, the change events can also include additional data such as a weighting factor, a categorization indicator, location information, locale information (e.g., for determining dialects of language usage), and word usage information. The additional data may be derived from the user's interaction with the local device or may be automatically generated by the system.

In some cases, event aggregation module 230, can aggregate or categorize the events into a single grouping to allow communications module 250 to push the events to the master language processing system 140. In addition, any categorization, defined as a grouping of words or n-grams, enables customization of the language and complex model management. In at least one embodiment, language changes can be pushed down as a category, allowing different weights to each category as a whole. The ability to assign different weights to each category, for example, allows impact on the language models to be adjusted. In other embodiments, categories can be deleted, thus easily removing the word and n-gram set from the user's model without affecting the remaining model.

Local language models 235 can be associated with each device to locally process the user's inputs. These local language models only incorporate the events detected with the associated device. In some cases, the models may also access any local contact lists, local e-mails, local SMS/MMS texts, and other local text-based communications for developing the local language model.

Prioritization module 240 prioritizes the change events detected by event detection module 225. In some embodiments, the prioritization may be based on local contextual information such as network connections, current usage rates, power levels, or user preferences. Using information about the detected events and the priority of these detected events, synchronization module 245 can send the events individually, or in the aggregate, to master language processing system 140. In some embodiments, synchronization module 245 receives update instructions from master language processing system 140.

Communications module 250 sends and receives any updates to and from master language processing system 140. In some embodiments, communications module 250 monitors the current connection type (e.g., cellular or Wi-Fi) and can make a determination as to whether updates and events should be pushed or pulled. For example, if communications module 250 determines that a cellular connection is currently being used then any outgoing messages can be queued using queuing module 255. In addition to the current connection type, communications module may use other information such as event priority and/or user preferences when determining whether to push or pull data.

GUI generation module 260 generates one or more GUI screens that allow for interaction with a user of the language processing system. In at least one embodiment, GUI generation module 260 generates a graphical user interface allowing a user of the computing devices to set preferences, run training applications for training the language processing system, set device constraints, select temporary static language model additions, and/or otherwise receive or convey information between the user and the device.

FIG. 3 illustrates a set of components for master language processing system 140. According to the embodiments shown in FIG. 3, master language processing system 140 can include memory 305, one or more processors 310, power supply 315, user identification module 320, local model identification module 325, event analysis module 330, master language models 335, comparison module 340, synchronization module 345, and communications module 350. Other embodiments of the present invention may include some, all, or none of these modules and components along with other modules, applications, and/or components. Still yet, some embodiments may incorporate two or more of these modules and components into a single module and/or associate a portion of the functionality of one or more of these modules with a different module. For example, in one embodiment, the functionality of user identification module 320 and local model identification module 325 may be incorporated into a single module.

Memory 305 can be any device, mechanism, or populated data structure used for storing information as describe above with reference to memory 205. Memory 305 may be used to store instructions for running one or more applications or modules on processors 310. For example, memory 305 could be used in one or more embodiments to house all or some of the instructions needed to execute the functionality of user identification module 320, local model identification module 325, event analysis module 330, master language models 335, comparison module 340, synchronization module 345, and/or communications module 350.

User identification module 320 can be configured to identify the user. In accordance with various embodiments, a variety of methods may be used such as, but not limited to, log in credentials, telecommunication device identifiers, voice identification, visual recognition, and/or other techniques for identifying users. The same or different identification methods may be used at each device to identify the user when the user accesses the language processing system. Each user is associated with multiple devices that have local language models. Local model identification module 325 can be used to track the current state of each model.

As events are received from the various local language models associated with an individual, event analysis module 330 determines how the events should be processed and applied (e.g., sequentially based on a time stamp or based on an assigned event priority) to the master language models 335. While some embodiments may notify users of inconsistencies, other embodiments, automatically handle the changes and manage the language model. In some cases, system resources such as disk space can be used in making decisions on how to process and apply the events and/or whether to retain lists of words. In some embodiments, the changes to the master language models 335 can be tracked using a change log in a SQL database. In other embodiments, the changes are stored in an on disk change log. In addition to the events received from the local devices, other off-board personal data, such as website data, social networking data, social networking friend data (such as communications with friends), information from personal computing devices, data from Internet accessible documents (e.g., Google docs), and others may be utilized in building the master language models.

Comparison module 340 determines the current state of any of the user's local language models as compared to the current master language models. Using the state information that is determined by comparison module 340, information synchronization module 345 can determine whether to send updates (e.g., in batches) using communications module 350 or request that an entire local language model be replaced.

FIG. 4 is a flowchart illustrating a set of operations 400 for synchronizing local language models based on a master language model. In accordance with various embodiments, the operations illustrated in FIG. 4 may be performed by one or more components (e.g., processor 310) and/or modules (e.g., user identification module 320 or synchronization module 345). Identification operation 410 identifies a user and any associated devices that have local language models. Maintaining operation 420 builds and maintains master language models based on events recorded from the local language models identified in identification operation 410. The master language models are typically maintained in a cloud-based environment or other distributed server-client system.

Recordation operation 430 records any changes to the master language model based on changes such as new words, removed words, n-grams, and word/n-gram weights received from the associated user devices. Using synchronization operation 440, the various local models on the user devices can be synchronized. Language model synchronization enables an end user to use multiple devices and have the usage of each of those devices affect both the master model and the models on the other devices. Tablets, phones, televisions, and cars all include textual input that could take advantage of synchronization of language models. The end result is a better experience because a user's usage of one device affects the prediction the user will receive on another device.

Determination operation 450 determines whether new or reset devices have been detected. If so, determination operation 450 branches to restoration operation 460 where the entire master language model is provided to the new or reset device as a local language model. Any changes or events detected by this, or any other local language model, are used to update the master language model. If determination operation 450 determines that no new or reset device has been detected, the determination operation branches to recordation operation 430 where any changes to the master language model are recorded.

Consider the following example for applying the master language model to a new device. Suppose a user has been using a language processing system which allows the user to back up and synchronize a language model across multiple devices. The user uses the language processing system on an old mobile phone but purchases a new mobile phone. When the user launches language processing system on the new device, it asks for a set of login credentials. Once the user is logged into the existing language processing system account (or other identifying account, such as Facebook™), the local language processing system connects to the master language processing system and loads the master dynamic language model, which includes all usage from the old phone. As a result, the local language processing system retrieves all of the changes and incorporates them into the new device. As a result, when the user starts typing, the language model on the new phone makes predictions based on previous usage, and the user is provided with a better experience.

Consider the following example for synchronizing multiple devices in accordance with various embodiments of the preset invention: suppose a user purchases a new tablet to go with the user's mobile phone. The user's account is accessed and the local language model is synchronized with the master language model residing in the cloud. In some embodiments, the cloud or cloud infrastructure is just a server based system that can be distributed. As the user starts using the tablet to write emails, new words that are commonly used in the current region are loaded, as well as some new phrases. Then, when the user picks up the mobile phone and types a few characters of a recently loaded new word, the word shows up in her word choice list. If the user selects the word, the next word in the new phrase is given as a prediction option in the user's word choice list.

One advantage of various embodiments of the present invention is the ability to allow a user to keep a language model across multiple devices and keep it up to date over time. This enables users to purchase a new device and pick up where they left off, as well as keep word use consistent across multiple devices. Various embodiments of the present invention also enable this information to be used to improve default, or shared, language models by allowing methods of analysis of actual user language models across multiple devices.

Various embodiments of the present invention may provide for a messaging system to synchronize change events that are determined to be of high importance between multiple devices. FIG. 5 illustrates a set of operations 500 for utilizing a high priority messaging system in accordance with various embodiments of the present invention. Priority determination operation 510 determines the priority of change events at a local language model. High priority change events (e.g., new words and n-grams added to the language model) are immediately sent to the master processing system via a real-time connection (e.g., TCP connection) in high priority sending operation 520. In some embodiments, events that significantly affect the weight of a word in a prediction engine could be determined to be high priority.

The master processing system updates the master language model with these change events and pushes the changes to the local language models during synchronization operation 530. Lower priority change events are sent to the master processing system (e.g., via batch messaging) at a later time using low priority sending operation 540. The master processing system updates the master language model with these change events and pushes the changes to the local language models during synchronization operation 550.

In some embodiments, the master processing system can consolidate language model changes both from a single device and from multiple devices. For example, if there are three devices synchronizing, the master model can consolidate a set of changes from the first and second devices for the third device. In some cases, the system can combine and/or aggregate common events as well as drop events that are no longer are applicable based on usage and/or time. The same priority may be applied to all change events in some embodiments. While in other embodiments, each event, or groups of events, can have different priorities. The local devices can use the event priority to create updates based upon multiple considerations (for example network availability) and transmit the events based upon priority or in larger blocks. The master processing system can then process the events and send them down to the other devices.

Consider the following real-time synchronization example: suppose a user has a phone and tablet both with the latest version of the language processing system that has the ability to synchronize words in real-time. The user is writing an email to some friends on a tablet about his new favorite show, Battlestar Galactica. Battlestar is not part of the user's language model and thus the user has to type it in completely, along with the unrecognized word Galactica. The system detects the add word event and generates a message to send across the message system to the server. The server detects that the phone is also active and sends the event down to the user's phone. After the user finishes the email, he immediately receives a text from one of his friends on his phone, wanting to chat about Battlestar Galactica. The user picks up his phone to begin writing a response and when he begins typing Battlestar he notices that the system predicts it immediately, removing his need to type it in.

Some embodiments of the present invention also provide for a language processing system whereby a server-based subscription model for language updates utilized by a client. In at least one embodiment, the clients can determine the most optimal update scheduling using device level factors such as connection status (e.g., cellular or Wi-Fi) and/or user preferences. For example, more frequent updates can be applied if a determination is made that a high quality and free data pipe is available. Similarly, if there is only a low quality (e.g., constantly dropping, or EDGE) the system might delay synchronization of large data sets. In addition, for the high priority events where a good connection changes can be sent in real time the updates may occur more frequently, while a poor connection might result in the system either batching or dropping the events. In accordance with some embodiments, a device can be notified of a list of possible language model enhancements (e.g., dinosaur or street names), which are either manually, or automatically subscribed to, and then integrated into the local language models.

FIG. 6 is a flowchart illustrating a set of operations 600 for integrating server-based subscription models in accordance with one or more embodiments of the present invention. Rules specifying when a local language model is to be automatically updated are referred to herein as a “subscription” and the periodic changes that are sent to the client and used to update the local language model under a subscription as “subscription packages.” Subscriptions can be class-based (e.g., download the language associated with a country upon entry into the country) or topic specific (e.g., receive all updates associated with the Denver Art Museum). In accordance with various embodiments, a subscription package (i.e., the actual updates) could be a batch binary set of events, a batch of text based events, or a set of either. Subscription packages are automatically sent to the user upon the receipt of the system by a triggering event, which as set forth below may be location-based, event-based, community-based, etc. In accordance with various embodiments, subscription updates typically include a first download at the time the user accepts the subscription, followed by periodic or occasional updates to include changes.

In some embodiments, for example, the user can navigate through a GUI presenting one or more categories, settings, options, or available subscription packages. The GUI can include settings to drive location based subscriptions, a manual list of available options based upon both the location of the user, and/or the total list of available subscriptions. The GUI can present notifications to a user to subscribe based on location. For example, as a user moves into a museum or other location, the system detects a list specifically for the location and prompts the user for selection.

As illustrated in FIG. 6, receiving operation 610 receives a triggering event for updating a language model by adding (possibly temporarily) additional words. In some embodiments, the triggering event can be a broadcast signal indicating an identifier associated with a set of additional words. For example, an exhibit in a museum may broadcast a signal identifying a subscription package having common set of words for the exhibit the user has just entered. The broadcast may be an identifier which can be used to download the subscription package from a remote server. In other cases, the broadcast may include the common set of words itself. Other examples of triggering events can include a user scanning a 1-D or 2-D barcode (e.g., on a sign, advertisement, or magazine) or a GPS location. The subscription packages can be automatically or manually accepted. Then, sending operation 620 sends the acceptance to the master language processing system where the subscription package is added to the master language model during update operation 630. The local model on the user's device is then updated using synchronization operation 640.

In some embodiments, the local language processing system (i.e., the client running on the end user's device) can use current language utilization as the triggering event to determine which models to update. In this case, language-based updates can be made available to the client from the server-based system (i.e., the master language processing system), and the client would use the active languages to determine if the update should be fetched. One benefit is that the enhancements are only downloaded for the languages the user is actively using, even though the user may have used other languages that have updates. When a user switches languages the system would determine if the server notified the device of updates for that language and process any updates.

Consider the following example, where a user's phone retrieves a list of subscriptions available from the server. The local language processing system detects that the user is currently using English and is in the US locale. The client determines all of the appropriate English subscriptions available and subscribes to them. The client downloads the current updates for the user's device. As a result, the user finds that the device now predicts the name of his favorite musician that it did not before. When the user switches to his native French, the client determines all of the appropriate French subscriptions available and subscribes to them. The next day the server notifies the clients of updates to the English and French models that it had subscribed to. Because the device is still set to French, the device updates the French subscriptions and marks the English subscriptions as available when the user switches back to English.

In some embodiments, location and/or crowd sourcing can be used as triggering events to determine subscription packages for download. For example, when a user lands in Paris, the French subscription package can be downloaded and/or activated. As an example of crowd sourcing, a determination can be made from those who are in your geographic location which packages should be downloaded and/or activated. That is, if a majority of people within a certain geographic area have voluntarily configured their mobile device with a particular subscription, the system may recommend the subscription to a user, or automatically add that subscription to a user's device. In such a case, the triggering event for the download is a percentage of a population within a certain geographic area having a subscription. Depending on the specific restrictions such as distance and/or time may also be applied in specifying the triggering conditions.

Various embodiments allow for different mechanisms for the management of the subscriptions. For example, in some cases, the end user can manage subscriptions either in the application or through a web based system. Various graphical user interfaces may be created which allow the user to select for manual or automatic updates and switching. FIG. 7 is a screenshot of a representative graphical user interface 700 that is generated by the GUI generation module 260 that allows a user to manage subscriptions for a user's mobile device. The user interface 700 includes various radio buttons and fields that allow a user to modify settings associated with subscriptions for automatically updating a local language model. For example, in a region 710 the user may define various settings associated with foreign language subscriptions. In accordance with various embodiments, the user can choose to automatically subscribe based upon language usage, and to keep the device updated based upon location. The user can also choose to manually subscribe based on language and/or location, either having them enter settings to change the options or to prompt the user when new subscriptions become available.

In a region 720, the user may define various settings associated with location-based subscriptions. Radio button 722 allows a user to select automatic location-based updates that are triggered by arrival of the mobile device in a new city and radio button 724 allow a user to select automatic location-based updates that are triggered upon arrival of the mobile device in a new country. Radio button 726 allows a user to specify whether they are interested in receiving location-based updates that are associated with a landmark or point of interest (e.g., museum, library, civic building). An associated drop-down menu 728 allows the user to specify the range at which the location-based update is triggered by the landmark or point of interest. For example, the user may specify that an update should automatically occur when the user enters a region within 1 km from the landmark or point of interest.

In a region 730, the user may define various settings associated with social subscriptions. For example, drop-down menu 732 allows a user to identify groups of friends from a social networking service, such as Facebook®, with which the user would like to maintain a communal language model. In this fashion, terms such as nicknames that are created by a user within a group of friends and added to a local language model are automatically propagated to others within the group of friends. Other social networks such as Twitter, Google Plus, Path, Blogger, Orkut, Sina Weibo, and others can also be used in some embodiments.

In a region 740, the user may define various network or device settings that apply to the subscription packages. For example, radio button 742 allows a user to specify that all packages should only be downloaded when the user's mobile device is connected to a Wi-Fi or other low-cost network connection. Radio button 744 allows a user to specify that all packages should occur between certain hours when the user is unlikely to be using their mobile device. Dropdown menu 746 allows the user to specify whether the defined subscriptions apply only to the present device, or to all devices owned by the user. For example the user might wish to only use Wi-Fi to download the subscriptions to not use up their data plan. Due to the proliferation of free Wi-Fi the user can jump onto a public Wi-Fi and download the available updates that have been marked on the local device for the end user. The user can also utilize other network based systems such as a local Bluetooth network to transmit the data to other devices or from a centralized server.

In some embodiments, the system can utilize network conditions. For example, if the system detects that the user is currently on what it determines is either a poor or metered connection updates would not be processed. When the system determines the user is on either a higher quality and/or un-metered connection the system would update the appropriate enhancements.

In a region 750, the system presents the user with the added cost of the subscription options that are selected by the user. The cost is dynamically updated by the system as the user defines the various settings associated with subscription updates. If the user agrees to accept the displayed price, the system may generate one or more graphical user interface screens (not shown) that accept payment information for those subscriptions which require payment. Various fee schedules, rates, and/or plans could be used in various embodiments. For example, subscriptions fees could be based over time (e.g., a monthly or yearly charge for usage), a one-time fee for the usage for the entire system, a one-time fee for each service, or a fee for each landmark individually.

FIG. 8 illustrates a set of information 800 that may be associated with each user in accordance with various embodiments of the present invention. As illustrated in FIG. 8, a user record can include a user ID, a local ID, a local device version, current location, current language ID, and any temporary language models being utilized by the local language processing systems.
